This tutorial details the steps required to enable and install the pre-existing peek & poke applications and check they are working as expected.

The aims of this tutorial are as follows :-

1. Setup environment
2. Change present working directory
3. Enable peek/poke application
4. Build, package & deploy on Zedboard
5. Launch terminal emulator
6. Check application is installed & working

Setup Xilinx design environment for the 2021.2 toolset.

Change the present working directory to be the project directory.

The Peek/Poke application is enabled through the configuration tool. Launch the tool to begin. The configuration tools should now present the root menu. Tip: Use the up & down arrow keys to nagivate the heirarchy, the left & right arrow keys to navigate the bottom menu, the enter key to select heirarchy/menu items, and the y & n keys to enable/disable components.

Navigate to apps and select it to enter the apps menu. Enable the peekpoke application. Exit the apps menu. Exit the configuration tool by exiting the root menu. Save the configuration on exit.

Rebuild the project to include the updated files, package it up ready for deployment, power cycle the Zedboard and deploy via JTAG.

Launch the MiniCom terminal emulator if not already running.

When the PetaLinux login prompt appears login using the root credentials.

Check the peek & poke applications have installed correctly by launching them. Check the peek application works by setting the outer two slides switches to their on position and reading the slide switch register. Check the poke application works by writing to the LED register, illuminating the outer four LED's and then the inner four.
